About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X75S
The MGCD50X75S is a JIS-standard round-body mini cylinder, double acting and double rod, with a variable air cushion at both ends. A 20 mm rod exits each cover with the same M18x1.5 male thread, so the two rod ends travel together and the effective area is the rod-side area in both directions: the output force is equal either way, about 824.3 N at 0.5 MPa and 1154 N at 0.7 MPa, with a theoretical maximum of 168.1 kgf at 1.0 MPa. The adjustable cushion decelerates the piston smoothly at each end, letting you run higher speeds or heavier loads without hard metal-to-metal stops, while the through-rod resists rotation and gives you a rear rod end for a stop flag, position switch trip, or a second load.
Construction follows the JIS mini-cylinder footprint: a riveted SUS304 stainless barrel with a hard-chrome plated carbon-steel rod and a two-way lubricant-storing piston seal. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof tested to 1.5 MPa (215 psi), from -20 to +70 C at 30-800 mm/s. The fitted magnet (the S code) allows CMSG, DMSG or EMSG switches to be clipped on for end-of-stroke sensing. As a realistic working figure, keep vertical loads to about 42 kg, roughly half the 84 kgf thrust at 0.5 MPa.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X75S Is Used
High-speed anti-rotation transfer
The 50 mm bore pushes 824.3 N each way at 0.5 MPa with equal force in both directions, while the through-rod keeps the tooling square and the adjustable cushions tame fast 800 mm/s arrivals at both ends.
Twin-load press with soft stop
Rod ends on both covers let you fixture two parts or add a rear anvil; the variable air cushion decelerates the stroke smoothly so each 1154 N (0.7 MPa) press ends without shock.
Rear-switch slide
The fitted magnet and rear rod end support a CMSG or DMSG switch and a stop flag on the same cylinder, ideal for a reciprocating slide that needs position feedback and cushioned reversal.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X75S the Right Cylinder?
Size the MGCD by force, not bore alone: this 50 mm bore delivers 824.3 N each way at 0.5 MPa, the second-largest in the MGCD range, so step down to MGCD40 if your load is lighter or up to MGCD63 (1400.9 N) if you need more. Choose MGCD when you need both a variable air cushion and a double rod; if your bore is 20-40 and a fixed bumper pad is enough, the MGD is the simpler double-rod option, and for a single rod with a cushion pick the MGC. The cushion is adjustable at both ends but only decelerates the piston near stroke end - it is not a lock, and the cylinder will not hold its load on air loss, so add an external rod lock or pilot check valve for holding. Mount with the FA flange or LB foot and use I or Y rod knuckles on the load (SDB and CB are not offered). The -S magnet in this model is required for CMSG/DMSG/EMSG sensing. Keep 75 mm of stroke clear at each rod end and support long or side-loaded tooling externally.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X75S FAQ
Because it is a double rod cylinder, both directions see the rod-side area: 824.3 N at 0.5 MPa and 1154 N at 0.7 MPa, with a theoretical maximum of 168.1 kgf at 1.0 MPa. It is double acting, runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof tested to 1.5 MPa (215 psi), and operates from -20 to +70 C at 30-800 mm/s. Ports are 1/4" and the rod thread is M18x1.5 on both ends.
The MGCD50X75S has an adjustable air cushion at both ends that decelerates the piston near each stroke end, allowing higher speeds and heavier loads than a plain stop; it is not a brake and does not hold the load on air loss. Unlike the MGD, which is a double-rod cylinder with fixed bumper pads, the MGCD cushion is adjustable, and unlike the MGC single-rod cushioned cylinder, the MGCD's through-rod gives equal force both ways plus a rear rod end. The fitted magnet also accepts CMSG, DMSG or EMSG switches.
